涤纶长丝染色不匀的原因及解决方法

The Reason and the Way of FDY Various Coloring

涤纶长丝染色不匀一般由于其结构原因,缺少亲水基因。并且与其生产的其它因素有关。解决方法也根据这两方面原因来改善,严格控制聚酯切片质量、熔体质量、侧吹风条件及油剂的性能、丝条的含油率、上油方式都是根据其结构原因;与其他因素有关系的如:升温过快、保温时间太短、布的循环速度过缓、燃料吸附不均匀、布容量远远超过标准容量。其防治方法:合理确定升温时间和保温时间,重新调整喷嘴压力;重新选择喷嘴隙缝及圆锥管以增加布速;合理选择染化料,拼色中如选用上染速率相差较大的分散染料,则应适当地增加分散剂或染料;容布量适中。

The polyester fiber filament dyes is not uniform generally as a result of its structure reason, and lacks of the water affinity gene. rester slice qualitv, the r The solution also acts according to these two aspect reason to improve, the strict control poltion elevation of temperature time and the soaking time, readjust ment of the nozzle pressure; Choose ment of the spray nozzle gap and the conical tube increases Jiabu fast; The reasonable choice influences the material, puts together in the color like to select dyes the speed difference big disperse dyes, should increase the dispersing agent or the dye suitably; Rong Buliang is moderate.
